Water supply connections
If a water heater is installed in a closed water supply system, such as one having
a backflow preventer in the cold water supply line, means shall be provided to
control thermal expansion. Contact the water supplier or local plumbing inspector
on how to control this situation. Install a shutoff valve near the inlet of the water
heater for service and draining purposes.
Before connecting the water supply pipe to the water heater, open the shutoff
valve and clean out sand, debris, air, caulking material, etc. inside the pipe.
Connect to the water inlet, then check water flow.
Close the shutoff valve and clean the water filter.
Be sure to connect the water inlet and the hot water outlet as shown on the water
heater. If reversed, the water heater will not function.
Installation of unions or flexible copper connections are recommended on the
HOT and COLD water lines, so that the water heater may disconnect easily for
servicing if necessary.
Install a Check Valve between the water heater and the water shutoff valve. (See
illustration to the top left).
In regards to the HOT WATER OUTLET:
Connections between the water heater and point(s) of use should be as short and
direct as possible.
DO NOT use lead or non-approved plastic pipe.
NOTICE:
The flow rate of hot water may vary when more than two faucets
(appliances, fixtures, etc.) are being used simultaneously.
